CHECK-LINE COUPLING.

Specification of Letters Patent.

Patented May 13, 1919.

Application filed July 6, 1918. Serial No. 243,619.

To (4Z5 whom it may concern:

Be it known that I, PINCKNEY F. SoivrERs,

a citizen of the United States, residing at Stony Point, in the countyof Alexander and State of North Carolina, have invented new and usefulImprovements in Check-Line Couplings, of which the following is aspeciiication.

h This invention relates to check line couplers for harness and it hasfor its object to produce a device of this class which will be simple inconstruction and by the use of which the twisting of the check lines bycareless drivers will be avoided.

A further object of the invention is to produce a check line coupler ofsimple and efiicient construction in the construction of which swivelsare included with which the check lines and driving reins may beconnected.

A further object of the invention is to produce a check line coupler ofsimple and improved construction having the characteristics to be setforth.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope oftheclaim may be resorted to when desired.

In the drawing Figure 1 is a plan view of the improved coupler showingthe check lines and one of the driving reins connected therewith.

Fig. 2 is a perspective view of the coupler.

Fig. 3 is a longitudinal sectional view of the same.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The frame A of the improved device may be cast or otherwise formed frommetal in a neat and ornamental shape. As shown in the drawing one endbar 15 of said frame is straight, the opposite end bar 16 being curved,and the side bars 17 being also curved inwardly with respect to theframe. The curved end bar 16 is provided on opposite side faces thereofwith bosses 18, said bosses being longitudinally apertured to receive ashank 19 having at its outer end a loop or terret 20, the inner end ofthe shank being provided with a collar 21 abutting on the inwardlyextending boss 18 to retain the shank in position, it being obvious thatthe shank is free to rotate about its axis, thus constituting a swivel.The cross piece or end piece 15 of the frame is provided near the endsand on both sides or faces thereof with bosses 22, similar to the bosses18, and each pair of bosses 22 being likewise apertured for thereception of a swivel shank 23 carrying at one end a loop or terret 24and at the other end a collar 25.

The check lines 26 are connected with the loops or terrets 24, and thedriving rein 27 is connected with the loop or terret 20. By thisconstruction and arrangement a swivel connection is established betweenthe check lines and the driving rein, and the parts are not liable tobecome permanently twisted or otherwise disarranged.

What is claimed is p A check line coupler consisting of a frame, the endpieces of which are provided with alined bosses on opposite sidesthereof, one end piece having two pairs of bosses about equidistant fromthe ends thereof, and the other end piece having a single pair of alinedbosses about midway between the ends thereof, said bosses beinglongitudinally apertured, in combination with shanks extending throughthe respective bosses and swiveled therein, said shanks having terretsat their outer ends for connection, respectively, with a pair of checklines and a driving rein.

In testimony whereof I afiix my signature.
